Canon Powershot G11 Digital Camera: Field Test Report

Peter Burian tests this premium-grade camera with 10MP resolution to determine how it compares to the very popular G10

One of the top rated digicams on the market, the 14.7 megapixel PowerShot G10 was recently replaced by the G11, with lower resolution said to provide superior image quality. The G10 was definitely an ideal second camera for serious photographers. In fact, this is the one that many of the pros carried when we went out for dinners while working at a week-long photo seminar in Dubai. (Also see Jack Neubart’s Canon PowerShot G10 Review here at Photocrati.com)

After testing the G10, I fell in love with that camera and bought one for my own use. While it received rave reviews about its conventional controls and low ISO quality, most test reports complained about its high ISO performance.

The 14.7 megapixel G10 was a highly-rated camera and produced fabulous images at low ISO but the G11 is even more desirable in some aspects. While resolution is lower at 10 MP, most reviewers agree that this is plenty for a digicam with built-in lens. (G11; ISO 100; f/8; 1/40 sec.)

In my own review for a Canadian magazine, I made the following comment about the G10: By ISO 800, images made in low light are still very sharp but very grainy although that’s not a problem in 5×7″ prints. At higher ISO, JPEG quality really suffers due to speckling and some smearing of fine detail by Noise Reduction processing. At ISO 800+, slightly better results are possible with Raw capture since Noise Reduction and Sharpening can be set to the optimal level in the converter software.

Most technical experts indicated that the problem was caused by the excessively small pixels (photosites). Apparently the engineers at Canon agreed since the company responded by replacing the G10 with the G11, with substantially lower 10 megapixel resolution provided by a new High Sensitivity sensor. That step made sense of course, since it allowed for larger photosites – with greater light gathering ability – for superior results at high ISO. (more…)

First Light: Canon EOS 7D

I’ve just started experimenting with the new ::amazon(“B002NEGTTW”, “Canon EOS 7D”)::, which is an interesting beast–an APS 1.6x crop camera with 18 megapixels. Many folks, some of whom don’t appear to have used the camera, have criticized this camera as going too far along the megapixel path at the expense of ISO. To me, the “right” trade-off between those two features depends a lot on the specific job you’re doing. One of the things that interests me about the 7D is that it can serve as a lightweight backup for shooting birds and for occasional wildlife work.

For that purpose, I want good high-ISO performance (but I may not need world-class). I also want a lot of cropably-delicious little pixels–for anything else I’ll do with the camera, I’ll have a tripod.

I don’t think of the 7D (as some have suggested) as a “bad upgrade to the 5D Mark II”, I think that misses the point of this camera entirely. I think of it sort of as a “1D lite” the way that the 5D Mark II is sort of a “1Ds lite”. Of course, I have yet to discover if the 7D lives up to that standard, but I have a few good first impressions.

First, let me share with you a few badly-controlled handheld shots from my living room. Before you go look, let me apologize that the 1600 image isn’t pin-sharp because of camera movement, you should be able to get a sense of the noise characteristics despite these flaws. (more…)

Canon EOS 1Ds Mark III Review: Field Test Report

Still the EOS to beat.

Canon EOS 1Ds Mark III - front. This is a rugged camera, with everything needed to deliver top quality images from day one. Granted, the heavy-duty battery gives it a large footprint and considerable heft, but still this is one camera you'd be proud to be seen with. Copyright ©2009 Jack Neubart. All rights reserved.

I’ve been working with Canon EOS single-lens-reflex cameras since they burst upon the scene. Well, actually, since shortly before, when I and other members of the photo press were introduced to the very first one-the EOS 1-on a top secret junket in Bar Harbor, Maine, many, many moons ago. Back then the photo press consisted entirely of print publications and cameras were analog, or as we simply liked to call them, cameras.

Fast forward to the digital age-and the full-frame EOS 1Ds DSLR. The 1-series continues to be the ranking member in the EOS lineup, designed for every imaginable professional application, with durability, functionality, reliability, and consistency at the forefront. And you’ve no doubt heard of the EOS 1Ds Mark III (MkIII, for short), the current flagship. While not the newest EOS on the block, like the 5D Mark II, it shares a 21.1 megapixel CMOS sensor.

But more to the point, it maintains the longstanding tradition established by its progenitors. And since Photocrati is a new site, we thought we’d take this camera out for a spin and round out our experiences with the EOS, with newer cameras to come under our scrutiny when available. In the meantime, here goes. Oh, and at the outset, at roughly $7,000, we should also point out that this is not the cheapest camera out there. But you’re getting a lot of bang for your buck and a camera that will probably outlast you in the field. (more…)

Comparative Digital SLR Lens Review: Fast, Wide Aperture Lenses

Field Test Report

Peter Burian tests five lenses with great light gathering ability: the Canon EF 70-200mm f/4L IS USM, Tamron AF 70-200mm f/2.8 Di LD (IF) Macro, Tokina AF 50-135mm f/2.8 AT-X Pro DX, Nikon 17-55mm f/2.8G ED-IF AF-S DX and the Sigma AF 30mm f/1.4 EX HSM DC

Because most digital SLR camera owners demand compact, lightweight lenses, the vast majority of zooms feature a small maximum aperture. A typical kit lens is designated as f/3.5-5.6 indicating that the maximum aperture is quite small at the short end and becomes very small at longer focal lengths. In practical terms, that translates to moderate light gathering ability. The larger the numeral the smaller the opening in the lens and the less light that will reach the camera’s digital sensor.

A wide aperture lens is ideal for fast shutter speeds in low light conditions when you cannot use flash or a tripod. Shooting at f/2.8 allowed me to get many sharp photos at 1/125 sec. during a stage performance, using ISO 1000. With a more typical (smaller) aperture, much higher ISO levels would have been required for the same shutter speed and the images would have been seriously degraded by digital noise.

Canon PowerShot G10 Review

A 14.7 MP pocket-size point-and-shoot even the pros use.

I don’t know of any point-and-shoot camera that commercial advertising shooters have used more than Canon’s PowerShot G-series. Yes, there are other very capable point-and-shoots out there, but none has garnered the G-series’ rep. As with its predecessors, the G10 remains the flagship in Canon’s point-and-shoot lineup, and as such, this camera proudly carries the colors into the heat of battle.

The G10 ups the ante in resolution, compared with earlier models in the G-series, delivering 14.7 megapixels (MP). That gives you enough real estate for cropping. Granted, it’s a CCD chip. Chatter on the Net is that the next G will be the G-whiz wunderkind, with a CMOS sensor adding new vitality into this series. (With that said, should you buy the G10 or wait? Well, you’ll need to read further.) (more…)

Canon EOS 40D Review: Field Test Report

Canon’s enthusiast-level series has included the EOS 10D, 20D and 30D, each boasting some improvement over its predecessor. The most recent DSLR in this range — prior to the EOS 50D — the 10 megapixel EOS 40D definitely qualified as a substantial upgrade over the 8 megapixel EOS 30D. Aside from higher resolution, the EOS 40D benefits from a great deal of new technology, such as an improved CMOS sensor, a faster DIGIC III processor plus a huge buffer (temporary storage bank) that allows for taking numerous shots at a blazing 6.5 frames per second. Several other amenities also make the EOS 40D more desirable than the earlier EOS 30D, including an automatic sensor cleaner, an Auto ISO option, a larger/brighter viewfinder, a 3″ LCD screen, and Live View.

The EOS Digital Rebel T1i and the shfiting DSLR Market

Two days ago Canon announced the next revision of their popular Digital Rebel line, the ::amazon(“B001XURPQI”,”Canon EOS Digital Rebel T1i”)::, a.k.a. the Canon 500D. Briefly speaking, it offers 15 megapixels, 720i and 1080p video at 30 and 20 fps respectively, and pretty much all the other recent Canon body features (LiveView, dust reduction) as well. ISOs 100-3200 are offered by default, with expanded settings of H1 (about 6400) and H2 (about 12800) available if enabled, the sample images I’ve seen so far are quite impressive. It’s due to ship in May. Very impressive for the new “low end” of the Canon line, this leads me to talk about what I perceive as a narrowing of the DSLR market. (more…)
